Adrian McCarthy 38e2d9e6a1 Fix x64 build on Windows, which was broken by my refactor from last week.
No build bots build x64 on Windows yet, but this was spotted by another developer who emailed me directly.

Zachary Turner 8d8033c3b4 Fix a race condition when terminating inferiors on Windows.
If a breakpoint was hit in the inferior after shutdown had
started but before it was complete, it would cause an unclean
terminate of the inferior, leading to various problems the most
visible of which is that handles to the inferior executable would
remain locked, and the test suite would fail to run subsequent
tests because it could not recompile the inferior.

This fixes a major source of flakiness in the test suite.

Zachary Turner ddf0661b38 Fix log disable command in ProcessWindowsLog.
The implications of this bug where that "log disable windows" would
not actually disable the log, and worse it would lock the file handle
making it impossible to delete the file until lldb was shut down.

This was then causing the test suite to fail, because the test suite
tries to delete log files in certain situations.

Jason Molenda 63bd0db071 Clean up register naming conventions inside lldb.
"gcc" register numbers are now correctly referred to as "ehframe"
register numbers.  In almost all cases, ehframe and dwarf register
numbers are identical (the one exception is i386 darwin where ehframe
regnums were incorrect).

The old "gdb" register numbers, which I incorrectly thought were
stabs register numbers, are now referred to as "Process Plugin"
register numbers.  This is the register numbering scheme that the
remote process controller stub (lldb-server, gdbserver, core file
support, kdp server, remote jtag devices, etc) uses to refer to the
registers.  The process plugin register numbers may not be contiguous
- there are remote jtag devices that have gaps in their register
numbering schemes.

I removed all of the enums for "gdb" register numbers that we had
in lldb - these were meaningless - and I put LLDB_INVALID_REGNUM
in all of the register tables for the Process Plugin regnum slot.

This change is almost entirely mechnical; the one actual change in
here is to ProcessGDBRemote.cpp's ParseRegisters() which parses the
qXfer:features:read:target.xml response.  As it parses register
definitions from the xml, it will assign sequential numbers as the
eRegisterKindLLDB numbers (the lldb register numberings must be
sequential, without any gaps) and if the xml file specifies register
numbers, those will be used as the eRegisterKindProcessPlugin
register numbers (and those may have gaps).  A J-Link jtag device's
target.xml does contain a gap in register numbers, and it only 
specifies the register numbers for the registers after that gap.
The device supports many different ARM boards and probably selects
different part of its register file as appropriate.

Stephane Sezer 38a1b7ea58 Move WindowsDYLD to the Plugins/DynamicLoader directory.
Summary:
This commit moves the Windows DyanamicLoader to the common DynamicLoader
directory. This is required to remote debug Windows targets.

This commit also initializes the Windows DYLD plugin in
SystemInitializerCommon (similarly to both POSIX and MacOSX DYLD
plugins) so that we can automatically instantiate this class when
connected to a windows process.

Test Plan: Build.

Zachary Turner 48b475cbaa Fix warnings generated by clang-cl.
There were a couple of real bugs here regarding error checking and
signed/unsigned comparisons, but mostly these were just noise.

There was one class of bugs fixed here which is particularly
annoying, dealing with MSVC's non-standard behavior regarding
the underlying type of enums.  See the comment in
lldb-enumerations.h for details.  In short, from now on please use
FLAGS_ENUM and FLAGS_ANONYMOUS_ENUM when defining enums which
contain values larger than can fit into a signed integer.

Zachary Turner 00998f0beb Solve hang on Windows when lldb fails to launch the process.
The DebuggerThread was detecting the launch error, but it was
ignored by ProcessWindows::DoLaunch, causing LLDB to wait forever
in the debugger loop.

This fixes the test case that explicitly attempts to launch a
process from a non-existant path.

Earlier this week I was able to get clang-cl on Windows to be

Zachary Turner 39cc7d4437 Don't use AVX/XSTATE API on Windows.
CopyContext is necessary to safely get the XState, but LLDB doesn't currently
use the XState. CopyContext is available as of Windows 7 SP1, so it can't be
used on Vista.  Furthermore, it requires the Windows 8 SDK it compile,
making the baseline for compiling and running LLDB higher than necessary.

Zachary Turner f194c50fc3 Some fixes for thread stepping on Windows.
This hooks up the changes necessary to set the trap flag on the
CPU and properly manage the process and thread's resume state
and private state so that the ThreadPlan does its thing.

Stepping still doesn't work as of this change, because there are
some issues with stack frames where it doesn't update the thread's
frame list correctly when it breaks inside of a function, but
I will try to fix that separately.

Zachary Turner c8761f4807 Remove a lock acquisition from ProcessWindows::OnExitProcess.
This was causing a race condition where DoDestroy() would acquire
the lock and then initiate a shutdown and then wait for it to
complete.  But part of the shutdown involved acquiring the same
lock from a different thread.  So the main thread would timeout
waiting for the shutdown to complete and return too soon.

The end result of this is that SBProcess::Kill() was broken on
Windows.
